Methods of uplink channelization in LTE

ABSTRACT

Slot-level remapping physical uplink control channels into two resource blocks, respectively located at two slots of a subframe, are generally adapted to a 3GPP LTE physical uplink. ACK/NAK resource blocks may be applied by the extended cyclic prefix, adapted to a complex 3GPP LTE physical uplink where mixed resource blocks (where the ACK/NAK and CQI channels coexist) may be applied by the normal cyclic prefix, and adapted to a complex 3GPP LTE physical uplink where mixed resource blocks (where the ACK/NAK and CQI channels coexist) may be applied by the extended cyclic prefix.

TECHNICAL FIELD

The present disclosure relates to a method and a circuit for physicaluplink transmission for 3GPP long term evolution (LTE), and morespecifically, to a method and a circuit generally adept at remappingphysical uplink control channels for both of a resource block containingacknowledgement and non-acknowledgement (ACK/NAK) channel and a mixedresource block containing the ACK/NAK channels and channel qualityindication (CQI) channels.

BACKGROUND

Orthogonal Frequency Division Multiplexing (OFDM) is a popular wirelesscommunication technology for multiplexing data in the frequency domain.

The total bandwidth in an OFDM system is divided into narrowbandfrequency units called subcarriers. The number of subcarriers is equalto the FFT/IFFT size N used in the system. Generally, the number ofsubcarriers used for data transmission is less than N because some ofthe subcarriers at the edge of the frequency spectrum are reserved asguard subcarriers, and generally no information is transmitted on theseguard subcarriers.

The 3^(rd) Generation Partnership Project Long Term Evolution (3GPP LTE)project seeks to improve the Universal Mobile Telecommunications System(UMTS) mobile phone standard to cope with future requirements. In thestandards of the physical uplink of 3GPP LTE, one type of the resourcesused for transmitting the physical uplink control channel (PUCCH) isknown as a cyclic shift (CS) for each OFDM symbol. One of importantaspects of the system design is resource remapping on either a symbol,slot or subframe-level.

The following three references are exemplary of the practice(s)described:

-   -   [REF1] R1-081155, “CR to 3GPP spec 36.211 Version 8.1.0,”        RAN1#52, February 2008, Sorrento, Italy, describes the standards        of the physical channels for 3GPP, and chapter 5.4.1 therein        illustrates slot-level remapping for the acknowledgement and        non-acknowledgement (ACK/NAK) channel in the physical uplink of        3GPP LTE system.    -   [REF2] R1-080983, “Way-forward on Cyclic Shift Hopping Pattern        for PUCCH,” Panasonic, Samsung, ETRI, RAN1#52, February 2008,        Sorrento, Italy, discloses methods for remapping either a        resource block containing only ACK/NAK channel or a resource        block containing both CQI and ACK/NAK channels.    -   [REF3] R1-073564, “Selection of Orthogonal Cover and Cyclic        Shift for High Speed UL ACK Channels,” Samsung, RAN1#50, August        2007, Athens, Greece, teaches a scenario for data transmission        for high speed uplink ACL/NAK channel by using a subset of the        combination of the cyclic shift and the orthogonal cover.    -   [REF4] R1-080707, “Cell Specific CS Hopping and Slot Based CS/OC        Remapping on PUCCH,” Texas Instruments, Feb. 11-15, 2008,        Sorrento, Italy, teaches cyclic shift (CS) hopping and slot        based cyclic shift/orthogonal covering (CS/OC) remapping for        PUCCH format 0 and 1, i.e. in the context of uplink ACIC/NAK        transmissions in correspondence to downlink packets.

The methods of the slot-level resource remapping proposed, for example,in references [REF2] and [REF3] have been included in the 3GPP standardsas shown in reference [REF1]. One of the shortages of transmissioncapacity in wireless telecommunication networks is that the contemporaryremapping methods for resource blocks containing control channels aredesigned exclusively for either ACK/NAK resource blocks with theextended cyclic prefix or for normal cyclic prefix cases where a mixedresource block containing both of the ACK/NAK and CQI channels, but suchremapping methods are not applicable for both. This shortage intransmission capacity prevents the techniques from being readily adaptedto a complex 3GPP LTE physical uplink where ACK/NAK resource blocks maybe applied by the extended cyclic prefix, adapted to a complex 3GPP LTEphysical uplink where mixed resource blocks (where the ACK/NAK and CQIchannels coexist) may be applied by the normal cyclic prefix, andadapted to a complex 3GPP LTE physical uplink where mixed resourceblocks (where the ACK/NAK and CQI channels coexist) may be applied bythe extended cyclic prefix.

SUMMARY

It is therefore an object of the present disclosure to provide animproved method and an improved circuit for conducting physical uplinktransmission in order to overcome the above shortage which prevents thecontemporary techniques from being generally adapted to a complex 3GPPLTE physical uplink.

It is another object of the present disclosure to provide a method and acircuit, with an intra-cell randomization, generally compatible with acomplex 3GPP LTE physical uplink where ACK/NAK resource blocks may beapplied by the extended cyclic prefix, or adapted to a complex 3GPP LTEphysical uplink where mixed resource blocks (where the ACK/NAK and CQIchannels coexist) may be applied by the normal cyclic prefix, or adaptedto a complex 3GPP LTE physical uplink where mixed resource blocks (wherethe ACK/NAK and CQI channels coexist) may be applied by the extendedcyclic prefix.

DETAILED DESCRIPTION

A simplified example of data transmission/reception using OrthogonalFrequency Division Multiplexing (OFDM) is shown in FIG. 1.

At the transmitter, the input data to be transmitted is modulated by aquadrature amplitude modulation (QAM) modulator 111. The QAM modulationsymbols are serial-to-parallel converted by a serial-to-parallelconvertor 113 and input to an inverse fast Fourier transform (IFFT) unit115. At the output of IFFT unit 115, N time-domain samples are obtained.Here N refers to the sampling number of IFFT/FFT used by the OFDMsystem. The signal transmitted from IFFT unit 115 is parallel-to-serialconverted by a parallel-to-serial convertor 117 and a cyclic prefix (CP)119 is added to the signal sequence. The resulting sequence of samplesis referred to as the OFDM symbol. Serial to parallel convertor 113 usesshift registers to convert data from serial form to parallel form. Datais loaded into the shift registers in a serial load mode, and is thenshifted parallel in a shift mode with a clock signal.

At the receiver, the cyclic prefix is firstly removed at cyclic prefixremover 121 and the signal is serial-to-parallel converted byparallel-to-serial convertor 123 before feeding the converted parallelsignal into fast Fourier transform (FFT) transformer 125. Output of FFTtransformer 125 is parallel-to-serial converted by parallel-to-serialconvertor 128 and the resulting symbols are input to QAM demodulator129. Parallel to serial convertor 123 uses shift registers to convertdata from parallel form to serial form. Data is loaded into the shiftregisters in a parallel load mode, and is then shifted serially in ashift mode with a clock signal.

The total bandwidth in an OFDM system is divided into narrowbandfrequency units called subcarriers. The number of subcarriers is equalto the FFT/IFFT size N. In general, the number of subcarriers used fordata is less than N because some of the subcarriers at the edge of thefrequency spectrum are reserved as guard subcarriers, and no informationis transmitted on guard subcarriers.

FIG. 2 is a block diagram of a simplified example of data transmission,data reception and signal processing stages using Orthogonal FrequencyDivision Multiplexing (OFDM). As shown in FIG. 2, the OFDM symbolsoutput from cyclic prefix (CP) 119 are further processed by signalprocessing unit_Tx 120 before being transmitted by the transmittingantennas. Similarly, the processed OFDM symbols transmitted from thetransmitter are firstly processed by signal processing unit_Rx 122before received by the receiving antennas. Signal processing unit_Tx 120and signal processing unit_Rx 122 perform signal processing respectivelyfor the transmitter and the receiver in accordance with certain signalprocessing schemes.

In the uplink of 3GPP LTE standards, one type of the resource used inthe uplink control channel (PUCCH) is known as a cyclic shift (CS) foreach OFDM symbol. PUCCHs are defined as channels carrying controlsignals in the uplink, and PUCCHs may carry control information, e.g.,channel quality indication (CQI), ACK/NACK, hybrid automatic repeatrequests (HARQ) and uplink scheduling requests.

The physical uplink control channel, PUCCH, carries uplink controlinformation. All PUCCH formats use a cyclic shift (CS) of a sequence ineach OFDM symbol. FIG. 3 is an illustration showing an example ofmultiplexing six user equipments (UEs) into one resource blockcontaining channel quality indication (CQI) signals within one slot. InFIG. 3, the PUCCH occupies twelve subcarriers in the resource block andtwelve cyclic shift resources (c₀ through c₁₁) exist in the resourceblock. The CQI signals include both of CQI data signals (e.g., CQI datasignal 201) occupying several symbol elements (e.g., s₀) within the OFDMsymbols and CQI reference signals (e.g., CQI reference signal 202)occupying several symbol elements (e.g., s₁). Six UEs (i.e., UE 1through UE 6) are multiplexed in the resource block. Here, only six outof twelve cyclic shifts are actually used.

FIG. 4, cited from reference [REF3], shows the contemporary workingassumption on the transmission block of uplink ACK/NAK channels andreference signals. Here, the position of the reference signal long blockis not determined, therefore, FIG. 4 is only for illustrative purposes.ACK/NAK signals and the uplink reference signals (UL RS) for ACK/NAKdemodulation are multiplexed on code channels 301 constructed by both acyclic shift of a base sequence (e.g., Zadoff-Chu sequence) and anorthogonal cover. ACK/NAK signals and the uplink reference signals aremultiplexed on code channels 301 constructed by both of a Zadoff-Chusequence ZC(u,.tau.) and an orthogonal cover. For ACK/NAK channels, aZadoff-Chu sequence ZC(u,.tau.) with a particular cyclic shift .tau.,ZC(u,.tau.) is placed in sub-carriers and an orthogonal cover is appliedto time domain long block (LB). The IFFTs transform a frequency domainrepresentation of the input sequence to a time domain representation.The orthogonal cover may be used for both of UL RS and for PUCCH data,the actual code of the orthogonal cover is different from {w.sub.0,w.sub.1, w.sub.2, w.sub.3} which is used only for PUCCH data.

FIG. 3 shows an example of a contemporary mapping method exclusivelyadapted to resource blocks only containing CQI channels, and FIG. 4shows an example of a contemporary mapping method for ACK/ANCK channels.

One important aspect of system design is resource remapping on a symbol,slot or subframe-level. The slot-level resource remapping methods havebeen proposed in, for example, references [REF2] and [REF3], and havebeen included in the current Change Request to the specification in 3GPPTS 36.211 version 8.1.0. Section 5.4.1 of that document, which includesthe slot-level remapping of the ACK/ANCK channel in the uplink controlPUCCH channel of LTE, is reproduced below for ease of reference:

“5.4 Physical Uplink Control Channel

. . . The physical resources used for PUCCH depends on two parameters,N_(RB) ⁽²⁾ and N_(cs) ⁽¹⁾, given by higher layers. The variable N_(RB)⁽²⁾≧0 denotes the bandwidth in terms of resource blocks that arereserved exclusively for PUCCH formats 2/2a/2b transmission in eachslot. The variable N_(cs) ⁽¹⁾ denotes the number of cyclic shift usedfor PUCCH formats 1/1a/1b in a resource block used for a mix of formats1/1a/1b and 2/2a/2b. The value of N_(cs) ⁽¹⁾ is an integer multiple ofΔ_(shift) ^(PUCCH) within the range of {0, 1, . . . , 8}, whereΔ_(shift) ^(PUCCH) is defined in section 5.4.1. No mixed resource blockis present if N_(cs) ⁽¹⁾=0. At most one resource block in each slotsupports a mix of formats 1/1a/1b and 2/2a/2b. Resources used fortransmission of PUCCH format 1/1a/1b and 2/2a/2b are represented by thenon-negative indices n_(PUCCH) ⁽¹⁾ and

5.4.1 PUCCH Formats 1, 1a and 1b

For PUCCH format 1, information is carried by the presence/absence oftransmission of PUCCH from the UE. In the remainder of this section,d(0)=1 shall be assumed for PUCCH format 1.

For PUCCH formats 1a and 1b, one or two explicit bits are transmitted,respectively. The block of bits b(0), . . . , b (M_(bit)−1) shall bemodulated as described in section 7.1, resulting in a complex-valuedsymbol d(0). The modulation schemes for the different PUCCH formats aregiven by Table 5.4-1.

The complex-valued symbol d(0) shall be multiplied with a cyclicallyshifted length N_(seq) ^(PUCCH)=12 sequence r_(u,v) ^((α)) (n) accordingto:y(n)=d(0)·r _(u,v) ^((α))(n),n=0,1, . . . ,N _(seq) ^(PUCCH)  (1)where r_(u,v) ^((α))(n) is defined by section 5.5.1 with M_(sc)^(RS)=N_(seq) ^(PPUCCH). The cyclic shift α varies between symbols andslots as defined below.

The block of complex-valued symbols y(0), . . . , y(N_(seq) ^(PUCCH)=1)shall be block-wise spread with the orthogonal sequence w_(n) _(oc) (i)according toz(m′·N _(SF) ^(PUCCH) ·N _(seq) ^(PUCCH) +m·N _(seq) ^(PUCCH) +n)=w _(n)_(oc) (m)·y(n),  (2)where

-   -   m=0, . . . , N_(seq) ^(PUCCH)−1    -   n=0, . . . , N_(seq) ^(PUCCH)−1    -   m′=0, 1,        and N_(SF) ^(PUCCH)=4. The sequence w_(n) _(oc) (i) is given by        Table 5.4.1-1.

Resources used for transmission of PUCCH format 1, 1a and 1b areidentified by a resource index n_(PUCCH) ⁽¹⁾ from which the orthogonalsequence index n_(oc)(n_(s)) and the cyclic shift α(n_(s)) aredetermined according to:

In the present disclosure, novel slot-level remapping methods areproposed to provide a better intra-cell randomization, especially forACK/NAK resource blocks with extended cyclic prefix, and for normalcyclic: prefix cases with mixed resource block where the ACK/NAK and CQIcoexist in a single resource block. Method A and Method B are proposedas below.

Equations (8) and (9) above are referred by the present disclosure.

Aspects, features, and advantages of the disclosure are readily apparentfrom the following detailed description, simply by illustrating a numberof particular embodiments and implementations, including the best modecontemplated for carrying out the described subject matter. The subjectmatter of the disclosure is also capable of other and differentembodiments, and its several details can be modified in various obviousrespects, all without departing from the spirit and scope of thedisclosure. Accordingly, the drawings and description are to be regardedas illustrative in nature, and not as restrictive. The subject matter ofthe disclosure is illustrated by way of example, and not by way oflimitation, in the figures of the accompanying drawings.

FIG. 5 is a flow chart illustrating a transmitting method of physicaluplink channel signals in accordance with the embodiments of the presentdisclosure. In step 701, signal processing unit_Tx 120 allocates acyclic shift and an orthogonal cover to physical uplink controlchannels; in step 703, signal processing unit_Tx 120 maps in aslot-level, the physical uplink control channels into two resourceblocks respectively located at two slots of a subframe; and in step 705,the transmitting antennas transmits the mapped physical uplink controlchannels. The present disclosure introduces novel remapping methods forperforming step 703.

Method C

In one embodiment of the current disclosure, a slot-level remappingmethod, method C, is proposed. In this method, the resource indiceswithin the two resource blocks respectively in the two slots of asubframe to which the PUCCH is mapped are given by:

-   -   when (n_(s)) mod 2=0, resource indices of the physical uplink        control channels within a first slot of the two slots of the        subframe are established by:

$\begin{matrix}{{n^{\prime}\left( n_{s} \right)} = \left\{ {\begin{matrix}{{{{if}\mspace{14mu} n_{PUCCH}^{(1)}} < \frac{c \cdot N_{cs}^{(1)}}{\Delta_{shift}^{PUCCH}}},n_{PUCCH}^{(1)}} \\{{otherwise},{\left( {n_{PUCCH}^{(1)} - \frac{c \cdot N_{cs}^{(1)}}{\Delta_{shift}^{PUCCH}}} \right)\;{mod}\;\left( \frac{c \cdot N_{sc}^{RB}}{\Delta_{shift}^{PUCCH}} \right)}}\end{matrix};{and}} \right.} & (12)\end{matrix}$

$\begin{matrix}\begin{matrix}{{n^{\prime}\left( n_{s} \right)} = {f\left( {n^{\prime}\left( {n_{s} - 1} \right)} \right)}} \\{= \left\{ {\begin{matrix}{{{for}\mspace{14mu}{normal}\mspace{14mu}{cyclic}\mspace{14mu}{prefix}\mspace{14mu}{and}\mspace{14mu} n_{PUCCH}^{(1)}} \geq} \\{\frac{c \cdot N_{cs}^{(1)}}{\Delta_{shift}^{PUCCH}},{{\left\lbrack {{3\left( {n^{\prime}\left( {n_{s} - 1} \right)} \right)} + 1} \right\rbrack\;{mod}\;\left( {\frac{3N_{cs}^{RB}}{\Delta_{shift}^{PUCCH}} + 1} \right)} - 1}} \\{{otherwise},} \\\left\{ {d + \left\lfloor \frac{\left( {n^{\prime}\left( {n_{s} - 1} \right)} \right)}{c} \right\rfloor + {\left\lbrack {{n^{\prime}\left( {n_{s} - 1} \right)}\;{mod}\mspace{14mu} c} \right\rbrack \cdot \left( \frac{N^{\prime}}{\Delta_{shift}^{PUCCH}} \right)}} \right\} \\{\;{{mod}\;\left( \frac{c \cdot N^{\prime}}{\Delta_{shift}^{PUCCH}} \right)}}\end{matrix},} \right.}\end{matrix} & (13)\end{matrix}$where

${n^{\prime}\left( n_{s} \right)} = \left\{ \begin{matrix}{{\left\lbrack {{c\left( {n^{\prime}\left( {n_{s} - 1} \right)} \right)} + 1} \right\rbrack{{mod}\left( {\frac{{cN}_{cs}^{RB}}{\Delta_{shift}^{PUCCH}} + 1} \right)}} - 1} & {{{{for}\mspace{14mu} n_{PUCCH}^{(1)}} \geq \frac{c \cdot N_{cs}^{(1)}}{\Delta_{shift}^{PUCCH}}},} \\{\left\lfloor \frac{h}{c} \right\rfloor + {\left\lbrack {h\;{mod}\; c} \right\rbrack \cdot \left( \frac{N^{\prime}}{\Delta_{shift}^{PUCCH}} \right)}} & {otherwise}\end{matrix} \right.$for (n_(s)) mod 2=1, where

${h = {\left( {{n^{\prime}\left( {n_{s} - 1} \right)} + d} \right){{mod}\left( \frac{{cN}^{\prime}}{\Delta_{shift}^{PUCCH}} \right)}}},$with d=2 for normal CP and d=0 for extended CP. By introducing the abovestated equations and the parameter “d” for the mapping of the resourceindices, the present disclosure achieves a better randomization and abetter performance of the mapping of the resource blocks within thecommunication system.

$\begin{matrix}{{n^{\prime}\left( n_{s} \right)} = \left\{ {\begin{matrix}{{{{if}\mspace{14mu} n_{PUCCH}^{(1)}} < \frac{c \cdot N_{cs}^{(1)}}{\Delta_{shift}^{PUCCH}}},} & n_{PUCCH}^{(1)} \\{{otherwise},} & {\left( {n_{PUCCH}^{(1)} - \frac{c \cdot N_{cs}^{(1)}}{\Delta_{shift}^{PUCCH}}} \right){{mod}\left( \frac{c \cdot N_{sc}^{RB}}{\Delta_{shift}^{PUCCH}} \right)}}\end{matrix};\mspace{20mu}{and}} \right.} & (21)\end{matrix}$
